ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain EMBRAER airplanes as 

described previously. This proposed AD 

would require inspecting to determine 

the part number of the left- and righthand windshield temperature 

controllers. For airplanes equipped with 

certain windshield temperature 

controllers, this proposed AD would 

also require replacing the attaching 

hardware of the power cable terminals 

of the windshield temperature 

controllers with new, improved 

attaching hardware; inspecting the 

power cable terminals for signs of 

melting or damage to the terminals, 

cable insulation, or plastic crimping 

ring; and performing corrective actions 

if necessary. This proposed AD results 

from reports of smoke on the flight deck 

caused by damage from poor electrical 

contact due to loosening of the attaching 

hardware of the power cables of certain 

windshield temperature controllers. We 

are proposing this AD to prevent 

overheating of the power cable 

terminals of the windshield temperature 

controllers, which could result in smoke 

and fire on the flight deck. 

DATES: We must receive comments on 

this proposed AD by October 26, 2006.

Discussion 

The Ageˆncia Nacional de Aviac ̧a ̃o 

Civil (ANAC), which is the 

airworthiness authority for Brazil, 

notified us that an unsafe condition may 

exist on certain EMBRAER Model EMB–

135BJ, –135ER, –135KE, –135KL, and 

–135LR airplanes and Model EMB–145, 

–145ER, –145MR, –145LR, –145XR, 

–145MP, and –145EP airplanes. The 

ANAC has received reports of smoke on 

the flight deck caused by damage from 

poor electrical contact due to loosening 

of the attaching hardware of the power 

cable terminals of certain windshield 

temperature controllers. This condition, 

if not corrected, could lead to 

overheating of the power cable 

terminals of the windshield temperature 

controllers, which could result in smoke 

and fire on the flight deck. 

Relevant Service Information 

EMBRAER has issued Service Bulletin 

145–30–0043, Revision 02, dated May 

25, 2006; and Service Bulletin 145LEG–

30–0013, dated June 28, 2005. The 

service information describes 

procedures for replacing the attaching 

hardware of the power cable terminals 

of certain windshield temperature 

controllers, part number (P/N) 3801D2( 

), with new, improved attaching 

hardware; inspecting the power cable 

terminals for signs of melting or damage 

to the terminals, cable insulation, or 

plastic crimping ring; and performing 

corrective actions if necessary. 

Corrective actions include replacing any 

melted or damaged crimping ring, cable 

terminal, or cable. Accomplishing the 

actions specified in the service 

information is intended to adequately 

address the unsafe condition. 

The ANAC mandated the service 

information and issued Brazilian 

airworthiness directive 2006–05–01, 

effective May 23, 2006, to ensure the 

continued airworthiness of these 

airplanes in Brazil. 

FAA’s Determination and Requirements 

of the Proposed AD 

These airplane models are 

manufactured in Brazil and are type 

certificated for operation in the United 

States under the provisions of § 21.29 of 

the Federal Aviation Regulations (14 

CFR 21.29) and the applicable bilateral 

airworthiness agreement. Pursuant to 

this bilateral airworthiness agreement, 

the ANAC has kept the FAA informed 

of the situation described above. We 

have examined the ANAC’s findings, 

evaluated all pertinent information, and 

determined that we need to issue an AD 

for airplanes of this type design that are 

certificated for operation in the United 

States. Therefore, we are proposing this 

AD, which would require 

accomplishing the actions specified in 

the service information described 

previously. 

Clarification of Inspection Terminology 

The service bulletins specify to 

inspect for evidence of damage or 

melting. However, to eliminate any 

confusion about the proper type of 

inspection, we would require a 

‘‘detailed inspection,’’ which is 

consistent with the type of inspection 

specified in Brazilian airworthiness 

directive 2006–05–01. 

Clarification of Part Number (P/N) 

References 

The service bulletins specify that 

certain windshield temperature 

controllers, having P/N 3801D2( ), are 

affected. The parentheses indicate that 

the P/N might or might not contain a 

suffix letter. Although the service 

bulletins identified in the following 

table make it clear that the INU part 

numbers, as identified in Table 1 of the 

AD, are the primary identifiers of all 

affected INUs, we have determined that 

these various suffix references could 

cause confusion. Therefore, to address 

all references to suffix letters in the 

service bulletins, we have revised the 

AD to read ‘‘–850( )/–851( )’’ where 

applicable. 

Costs of Compliance 

This proposed AD would affect about 

689 airplanes of U.S. registry. The 

proposed actions would take about 1 

work hour per airplane, at an average 

labor rate of $80 per work hour. 

Required parts would be supplied from 

operator stock. Based on these figures, 

the estimated cost of the proposed AD 

for U.S. operators is $55,120, or $80 per 

airplane. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in subtitle VII, 

part A, subpart III, section 44701, 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 


sroberts on PROD1PC70 with PROPOSALS
56058 Federal Register / Vol. 71, No. 186 / Tuesday, September 26, 2006 / Proposed Rules 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We have determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that the proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket. See the ADDRESSES section 

for a location to examine the regulatory 

evaluation.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede an existing airworthiness 

directive (AD) that applies to all Airbus 

Model A300 B2, B4–100, and B4–200 

series airplanes. The existing AD 

currently requires supplemental 

structural inspections to detect fatigue 

cracking, and repair of cracked 

structure. This proposed AD would 

require revising the maintenance 

program by incorporating new and 

revised supplemental structural 

inspections, inspection intervals, and 

repairs; and repair of any damaged, 

cracked, or corroded structure; which 

would end the existing supplement 

structural inspections. This proposed 

AD results from a review of service 

history and reports received from the 

current supplemental structural 

inspection document program. We are 

proposing this AD to prevent reduced 

structural integrity of these airplanes 

due to fatigue cracking. 

DATES: We must receive comments on 

this proposed AD by October 26, 2006. 

ADDRESSES: Use one of the following 

addresses to submit comments on this 

proposed AD.
